OSFP (RHS/Flat Top) to QSFP-DD-400G-DAC-2M7FT 400G OSFP 4 x 100G PAM4 RHS/Flat Top to 400G QSFP-DD 4 x 100G PAM4 Passive Copper Twinax Cable, 2m (7ft)

The HT-manufactured OSFP (RHS/Flat Top) to QSFP-DD-400G-DAC-2M7FT compatible cable provides 400G connectivity for multi-vendor equipment. This 2m (7ft) version is a factory-terminated passive copper link without separate optical modules or patch cords, with an exact part number and length that can be matched directly to the equipment requirement.

Product Highlights

• HT-manufactured DAC assembly in 2m (7ft)
• 400G connectivity at 400Gbps
• Interface configuration: OSFP (RHS/Flat Top) to QSFP-DD
• Fixed length and part number: 2m (7ft), OSFP (RHS/Flat Top) to QSFP-DD-400G-DAC-2M7FT
• Cable construction: Passive Twinax
• Conductor specification: 28AWG
• Maximum power consumption: ≤0.1W
• Minimum bend radius: 40.5mm

The rated power consumption is ≤0.1W. Include this load in the host-port power and thermal budget, especially in densely populated switches. Maintain front-panel clearance and do not bundle the cable so tightly that it obstructs airflow around the connectors.

This assembly uses 28AWG conductors, PVC jacket, minimum bend radius 40.5mm. These mechanical characteristics affect how the cable should be dressed behind the equipment. Avoid sharp edges, excessive ties and repeated tight bends close to the connector boots.

The intended application is 400G Ethernet. Listed interface and protocol references include IEEE 802.3cd, OSFP MSA, QSFP-DD MSA, CMIS Rev4.0, SFF-8417. Confirm that the host firmware and port configuration support the same operating mode.

A passive DAC has no separate optical conversion stage. Its low-power, low-latency operation is useful for short equipment links, but the assembly must remain within the length and signaling mode accepted by both hosts.

OSFP (RHS/Flat Top) to QSFP-DD-400G-DAC-2M7FT provides 2m (7ft) for connections between separated rack units or nearby equipment positions. Plan the route around cable managers and power cords, keeping the assembly free from connector strain while avoiding a large obstruction in the airflow path.

OSFP (RHS/Flat Top) to QSFP-DD-400G-DAC-2M7FT is the longest of 4 verified length options in this family. Compared with OSFP (RHS/Flat Top) to QSFP-DD-400G-DAC-1.5M5FT at 1.5m (5ft), it provides 0.5m of additional reach for a longer vertical drop, a wider rack or an adjacent-cabinet route. Confirm that the complete path requires this length, because unused slack still needs supported, bend-safe storage.

For this Generic application, testing combines digital identification with actual traffic-link verification and electrical continuity, link stability and diagnostic readouts. Both ends are inspected for latch, boot and connector damage. If the project uses a specific hardware revision or a channelized port, send those details so that the intended configuration can be reviewed before shipment.

When ordering, specify OSFP (RHS/Flat Top) to QSFP-DD-400G-DAC-2M7FT, cable length 2m (7ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

Quality control includes connector appearance, cable identification and functional verification. Packing materials are selected to keep the connector housings and cable boots from taking impact during transport, and the coil is not compressed into an undersized bundle. Volume orders can include customer-specific labels and packing documentation.

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
